ECU的工作原理电子控制器ECU的工作过程复杂而有序,工作速度快捷而有条不紊,用几句话难以说明白。为了帮助大家建立一个初步的印象,下面以发动机电控单元ECU为例,简要介绍其工作原理。发动机启动时,电子控制器ECU进入工作状态,某些程序或操作指令从存储器ROM中调入中央处理单元CPU。这些程序可以控制燃油喷射、燃油泵工作电压、点火时刻等。在CPU控制下,一个个指令按照预先编制 ECU works Electronic controller ECU’s work process is complex and orderly, fast and orderly pace of work, with a few words hard to understand. In order to help you create a first impression, the following ECU ECU as an example, briefly describes its working principle. When the engine is started, the electronic controller ECU enters the working state and some programs or operation instructions are transferred from the memory ROM to the central processing unit CPU. These programs can control fuel injection, fuel pump operating voltage, ignition timing and more. Under the control of the CPU, one by one according to pre-programmed
